Final answer:
A likely food chain is grass -> deer -> human.
Step-by-step explanation:
A likely food chain would be: grass → deer → human. In this food chain, energy flows from the producer (grass) to the primary consumer (deer) and then to the secondary consumer (human). The grass is the producer because it converts sunlight into energy through photosynthesis. The deer is the primary consumer because it eats the grass, and the human is the secondary consumer because it eats the deer. This food chain follows the sequence of energy transfer through trophic levels.
